MINING SYSTEM.

Specicaton of Letters Patent.

Patented Dec. 23, 1919.

Original application filed August 10, 1917, Serial No. 185,604.. Divided and this application led November To all whom t may Concern.'

Be it known that I, ADoLri-I G. BAUER, a citizen of the United States, residing at Ouray, in the county of Ouray, State of Colorado, have invented certain new and useful Improvements in Mining Systems; and I do hereby declare the following to be a full, clear, and eXact description of the invention, suoli as will enable others skilled in the art to which it appertains to make and use the same.

This invention is an improvement in mining systems and is a division of the copending application filed August 10, 1917,

and bearing the Serial Number 185604 andi in which the construction of a mining car is described and claimed.

The invention has for one of its objects to provide a system whereby the operation of removing the muck from a tunnel after a blast is greatly facilitated by the saving of time and labor usually involved in loading the cars and conveying the same from the tunnel..

The invention has for another object the compacting of the load upon the foremost of a series of conveyers before this one is further handled, one object being to prevent spilling` of the load. This compacting is done by raising the sides so as t-o act on the load transversely and then by raising the inner end so as to act on the load longitudinally. As said inner end is laid upon the bottom of the conveyer next to the rear, in its rise it will relieve that conveyer of a portion of its load at the front end; and therefore a further object of this step may be said to be the clearing of the second conveyer for the insertion subsequently of its removable front end. As an adjunct to this step of compacting load longitudinally, the inner end of the first conveyer is lifted so that the load slides forward. The conveyer as a whole is then mounted on a truck and carried away.

The inventive idea involved is capable of receiving a variety of expressions one of which, for the purpose of illustrating the invention is shown in the accompanying drawing, wherein Figure '1 is a diagrammatic view iu plan, showing a number of conveyers in a tunnel previous to a blast. A

Fig. 2 is a side elevation thereof. l

Figs. 3, l and 5 are views similar to Fig.

serial no. 204,249.

2 showing the successive steps in the operationof removing muck from the tunnel after a blast.

In the use of the present system, a number of conveyers are employed such as specifically described and claimed in the above mentioned application and, broadly, said conveyers each include a body 10 adapted to be laid upon tracks 11 and having hinged sides 12 and end 13. The conveyers are first removed from the trucks 9, as described in the copending application, and laid upon the tracks 11 with their' sides 12 swung outwardly in an inclined position against the tunnel. The conveyers are so mounted in the tunnel that the hinged rear ends 13 thereof will be nearest the inner end of the tunnel and the hinged end of the innermost conveyer is swung to a substantially horizontal position resting upon the tracks 11. Each conveyer further includes a removable end (not shown) which is detached from the conveyer when the same is placed on the tracks and the hinged end of the next succeeding conveyer is swung to a position within the opened end of the innermost conveyer and overlapping the bottom thereof. When a sufficient number of conveyers have been so mounted in the tunnel it will be apparent that the bottom thereof will be covered so that when the blast occurs practically all of the muck will fall onto the series of conveyors, as illustrated in Fig. 3, it being understood that the force of the blast will act against only the sides and roof of the tunnel. After the blast the sides of the foremost conveyer are first swung upward to their normal positions in a manner set forth in the copending application. This will compact the load transversely thereof. The detachable end (not shown) is then mounted in position at the front of said conveyer. The conveyer is then lifted slightly at its rear inner end in any preferred manner, such as by chains 141 which may be connected to a suitable mechanism (not shown) and by tilting the conveyer, as shown in Fig. 4L, the muck resting upon the end 13 will slide forward into the body and be compacted longitudinally therein after which said end is swung upward to its closing position, and thereby a certain amount of the material at the front end of the next conveyer is removed therefrom. The conveyer may then be conveyed from the tunnel.

on a truck 9 or otherwise to the place of dumping, and it carries its compacted load without spilling. In the same manner each successive conveyor is loaded While laid out on the track its load compacted, and the Whole removed and it will be apparent that this system of removing muck from a tunnel Will greatly reduce the time and labor involved, as practically all of the actual loading of the conveyor is done by the blast itself.

Vliet is claimed is The herein described mining system consisting of first disposing a series of conveyers upon the bottom of a tunnel with the rear end of each lying upon the forward portion of the next conveyer in the series, then employing means to shatter the Walls and top of the tunnel whereby the material falls onto said series, then compacting the load on the foremost conveyer transversely, then compacting it longitudinally and removing a portion of the load from the front part of the conveyer next to the rear, then removing the foremost conveyer with its load, and s0 on throughout the series.

In testimony whereof7 I afliX my signature in the presence of two Witnesses.
